Duet 3 Paneldue not working

Visionary

I downloaded Duet2and3Firmware-3.xxx.zip when I did fallback procedure, but I'll try doing updating paneldue alone through Bossa.

@visionary i dont think the paneldue files are included in the Duet2and3Firmware-3.xxx.zip

Visionary

@jay_s_uk

Windows won't recognize USB connection on paneldue, so I don't seem to be able flash firmware that way. USB cable I used worked with mainboard.

jay_s_uk

@visionary get the appropriate zip from here https://github.com/Duet3D/PanelDueFirmware/releases/tag/3.2.11 and upload it to the systems tab in DWC. It should prompt you to update the firmware

Visionary

I think this might be a problem since I use a laptop, but I'm not sure If I'm suppose to connect both main power and PC USB to Duet at the same time and causing possibe ground loops or does the screen backlight stay off.

On dozuki:

If you have a PanelDue with a 7 inch TFT panel, then some PC USB ports and especially laptop USB ports may not be able to supply enough power to the PanelDue when the backlight is on. If you press Erase and Reset while the PanelDue it powered from your controller electronics, then the backlight should turn off, which should resolve the problem. Or you can disconnect the PanelDue control board from the TFT panel (unless you are using the integrated version), then upgrade the firmware, then reconnect it.

I managed to flash paneldue after I realized that I could use much shorter cable by taking the panel off from the printer. The panel now responds and I can switch between for example the console and control tab, but moving axes or homing does not work at all and the number of heaters/axes is still wrong.

@visionary have you got M575 P1 S1 B57600 in your config.g?

Visionary

@jay_s_uk

Should be as I haven't changed config and it was in my old config.

Visionary

I just noticed that with power from main PSU the Duet (both mainboard and paneldue) won't work properly:

Wrong number of axis/heaters on paneldue
Paneldue responds but doesn't allow to do anything
When main power is on, connecting through ethernet doesn't seem to work

But with just USB power the printer seems work as normal (however I can't test anything without main power).

@visionary sounds like you may have blown the 3.3v or 5v regulator. Can you confirm what lights are on when powered from the PSU? Also have a feel and see if anything gets hot

Visionary

@jay_s_uk

All LEDs are on continuously. Diagnostic LED is on too although its very dim.

@visionary said in Duet 3 Paneldue not working:

Diagnostic LED is on too although its very dim.

On a Duet 3, that normally means that the board isn't running any firmware.

Visionary

@dc42
When I used USB the board and panel work normally: I can even connect to it then through DWC, so it clearly has firmware on it. The diagnose LED (continuously on) is very dim with 24V main power when compared USB (blinking) powered brightness.

dc42

@visionary, are you powering anything else from the Duet's 5V supply other than the PanelDue? For example, a Raspberry Pi or an LED strip. I am wondering whether there is insufficient 5V power from the internal 5V regulator.

Visionary

@dc42

Only thing connected to 5V (in IO_x connectors) is paneldue i7. I have two inductive sensors NBB0,8-4M25-E2 and NJ2-12GM40-E as endstops on X- and U-axes, but those get their power from external 24V PSU. Other than that I have nothing unusual connected to mainboard. I tested with cheap multimeter 5V (and ground) output from IO-3 and got 4,88V.

BTW where is 5V regulator located on the board?

Visionary

The found out that one of the inductive sensors was the problem. Without it being connected paneldue showed correct information.

I'm not sure what is the exact cause. Too much current through GND-pin or input? Can I connect sensor GND to 24V PSU GND? Or would increasing/decreasing resistor value work?

My current wiring (Inductive sensor NBB0,8-4M25-E2-Y106003):

Visionary

I put voltage divider (10k and 4.7k resistors) between sensor and input on Duet and it seemed to fix the problem.
